Subjective bias in reports of poor work adjustment in depressed patients

Twenty-five depressed inpatients were asked to report their adjustment at work during the 4-month period preceding their hospitalization. Two separate reports were given: the first during the acute illness phase and the second one 10-28 days later, after symptomatic remission following standardized pharmacotherapy. Thirty-two percent more patient ratings showed absence of adjustment problems on the second report compared with the first. Significant differences between the 2 reports were found in 7 of the 9 items on the Structured and Scaled Interview to Assess Maladjustment, which is designed to assess specific aspects of maladjustment at work. The changes in the scores of maladjustment correlated with the changes in the scores of depressive symptoms, and 40% of the variation in maladjustment scores was accounted for by the pessimism item of the Montgomery-Asberg Depression Rating Scale. Much of the poor work adjustment reported by the acutely depressed patients thus seems to be caused by symptom-related subjective bias.

Cumulative adverse effects of diabetes mellitus and hypertension on coronary flow velocity reserve

BACKGROUND: this study aimed to assess the hypothesis that essential hypertension (EH) may increase coronary microcirculation dysfunction in patients with type 2 diabetes mellitus (DM). Microvascular dysfunction has been reported in patients with DM or EH. Discordant results have been reported on cumulative adverse effects of the simultaneous presence of DM and EH on coronary flow velocity reserve (CFR). METHODS: CFR were compared in 13 hypertensive diabetics (group 1), 12 normotensive diabetics (group 2), 11 hypertensive non diabetics (group 3) and 29 normotensive non diabetic patients (group 4). CFR was calculated using an intracoronary Doppler-tipped flow wire. RESULTS: CFR was significantly lower in patients with both DM and EH (2.2 +/- 0.4 in group 1 vs 2.8 +/- 0.5, 2.8 +/- 0.6 and 2.9 +/- 0.7 in groups 2, 3 and 4 respectively, p<0.01). The presence of hypertension reduced CFR in diabetic patients with angiographically abnormal but unobstructed coronary arteries (2.1 +/- 0.3 in hypertensive vs 3.1 +/- 0.2 in normotensive diabetic patients, p<0.02). No cumulative adverse effect was observed in diabetics with angiographically normal coronary arteries (2.3 +/- 0.6 in hypertensive vs 2.6 +/- 0.5 in normotensive diabetic patients, NS). Multivariate analysis revealed that combination of DM and EH (p<0.007) was independently related to CFR. CONCLUSIONS: the presence of hypertension appears to worsen coronary microangiopathy in diabetic patients with unobstructed coronary artery disease. The cumulative effect of EH and DM on CFR impairment has consequences for decision-making during coronary angioplasty and could identify patients at risk for cardiomyopathy.     

Post-traumatic aortic valve insufficiencies]

Aortic regurgitation due to closed chest trauma is rare. It is related either to a valve lesion itself (ruptured cusp) or to trauma of the ascending aorta (subadventitial rupture with prolapse of the underlying aortic valve cusp). Four cases are described, 2 men and 2 women aged 30 to 66 years, after severe injuries in road traffic accidents: three patients had rupture of the aorta and the other had isolated rupture of the non-coronary aortic valve cusp. This pathology is unique due to the pathogenic mechanism associated with multiple thoracic injuries (right costal flap, sternal fracture, pulmonary contusion ...). The polytraumatic context explains the diagnostic difficulties and the secondary importance of the valve problem. Late surgery of these lesions was conservative in 3 cases: valve replacement was necessary in 1 case. If the haemodynamic tolerance of the aortic regurgitation is good, surgery should be deferred until the polytraumatic emergency has been dealt with. Good surgical results, often with conservative procedures, encourage earl operation after the acute polytraumatic period.     

Influence of glucose control and improvement of insulin resistance on microvascular blood flow and endothelial function in patients with diabetes mellitus type 2

OBJECTIVE: The study was performed to investigate the effect of improving metabolic control with pioglitazone in comparison to glimepiride on microvascular function in patients with diabetes mellitus type 2. METHODS: A total of 179 patients were recruited and randomly assigned to one treatment group. Metabolic control (HbA1c), insulin resistance (HOMA index), and microvascular function (laser Doppler fluxmetry) were observed at baseline and after 3 and 6 months. RESULTS: HbA1c improved in both treatment arms (pioglitazone: 7.52 +/- 0.85% to 6.71 +/- 0.89%, p < .0001; glimepiride: 7.44 +/- 0.89% to 6.83 +/- 0.85%, p < .0001). Insulin-resistance decreased significantly in the pioglitazone group (6.15 +/- 4.05 to 3.85 +/- 1.92, p < .0001) and remained unchanged in the glimepiride group. The microvascular response to heat significantly improved in both treatment groups (pioglitazone 48.5 [15.2; 91.8] to 88.8 [57.6; 124.1] arbitrary units [AU], p < .0001; glimepiride 53.7 [14.1; 91.9] to 87.9 [52.9, 131.0] AU, p < .0001, median [lower and upper quartile]). Endothelial function as measured with the acetylcholine response improved in the pioglitazone group (38.5 [22.2; 68.0] to 60.2 [36.9; 82.8], p = .0427) and remained unchanged in the glimepiride group. CONCLUSIONS: Improving metabolic control has beneficial effects in microvascular function in type 2 diabetic patients. Treatment of type 2 diabetic patients with pioglitazone exerts additional effects on endothelial function beyond metabolic control.     

Perceived School Safety is Strongly Associated with Adolescent Mental Health Problems

School environment is an important determinant of psychosocial function and may also be related to mental health. We therefore investigated whether perceived school safety, a simple measure of this environment, is related to mental health problems. In a population-based sample of 11,130 secondary school students, we analysed the relationship of perceived school safety with mental health problems using multiple logistic regression analyses to adjust for potential confounders. Mental health problems were defined using the clinical cut-off of the self-reported Strengths and Difficulties Questionnaire. School safety showed an exposure–response relationship with mental health problems after adjustment for confounders. Odds ratios increased from 2.48 (“sometimes unsafe”) to 8.05 (“very often unsafe”). The association was strongest in girls and young and middle-aged adolescents. Irrespective of the causal background of this association, school safety deserves attention either as a risk factor or as an indicator of mental health problems.     

Values of the autopsy in the university hospitals illustrated by the casuistry

PURPOSE: Clinical autopsy rate have been declining since the 1950s, but it remains a useful investigation tool. METHODS AND RESULTS: Through six examples of our experience, we underline its interest for clinical, didactic and public health purposes. CONCLUSIONS: We try to understand the reasons for its decline and, as demonstrated, it can be attributed to a number of factors. These need to be addressed in order to reassert the status of the autopsy as an investigation and audit tool which is crucial to the future effectiveness of modern medicine.     

The ACE gene I/D polymorphism is not associated with the blood pressure and cardiovascular benefits of ACE inhibition

The insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene might have consequences for the risks of vascular diseases. We examined the ACE genotype and the effects of a perindopril-based blood pressure-lowering regimen on macrovascular events, dementia, and cognitive decline among hypertensive and nonhypertensive patients with a history of cerebrovascular disease. ACE I/D genotypes were measured in 5688 of 6105 individuals with previous stroke or transient ischemic attack who participated in the PROGRESS trial. The DD genotype was significantly (P<0.0001) less frequent in Asian subjects (Chinese and Japanese, 14.7%) than in non-Asian subjects (32.0%). Controlling for racial background, there were no associations between ACE genotypes and cerebrovascular disease history or cardiovascular risk factors, including baseline blood pressure. The ACE genotype was not associated with the long-term risks of stroke, cardiac events, mortality, dementia, or cognitive decline; neither did the ACE genotype predict the blood pressure reduction associated with the use of the ACE inhibitor perindopril. Similarly, there was no evidence that the ACE genotype modified the relative benefits of ACE inhibitor-based therapy over placebo. This study provides no evidence that in patients with cerebrovascular disease, knowledge of ACE genotype is useful for predicting either the risk of disease or the benefits of perindopril-based blood pressure-lowering treatment.
